If it is already declared as bug why don't you patch the server with the bug fix. Ask Oracle for specific path that fixes this issue.
If it is the bug then you should use the appropriate patch. However, if it is not the bug you should be able to get more information regarding the issue of integrity.
Thank you very much for the reply. If you have any idea, can you please let me know which patch we need to apply.
Sorry Venky, no idea...
But I thought Oracle support still supports version 18.104.22.168...
